Immune Complex Diseases
| Medical Definition: |
Group of diseases mediated by the deposition of large soluble complexes of antigen and antibody with resultant damage to tissue. Besides SERUM SICKNESS and the ARTHUS REACTION, evidence supports a pathogenic role for immune complexes in many other systemic immunologic diseases including GLOMERULONEPHRITIS, systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC) and POLYARTERITIS NODOSA. |
| Guide Notes: |
dis caused by deposition of antigen-antibody complexes with resultant damage to tissue; "immune complex" = IMMUNE COMPLEX see ANTIGEN-ANTIBODY COMPLEX |
